All lanes of the M25 are now open after a lorry fire - made worse as some of its 30-tonne load of plastic pellets spilled out.

The HGV burst into flames on the clockwise carriageway before J4 for Orpington this morning.

It led to delays of more than an hour-and-an-half during, with congestion back to J2 at the Darenth Interchange.

But the Highways Agency announced all lanes were opened just after 3pm.

Some of the lorry’s 30-tonne load of raw plastic pellets spread across the carriageway, meaning it had to be closed for safety reasons.

All traffic was earlier being held half a mile from J4 because of the blazing vehicle on the hard shoulder.

The fire had been put out and one lane reopened at just after 6.50am.

However, congestion continued to build as two lanes remained closed for recovery work.
